Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Figure 1, the warm and humid control system of a kind of agricultural greenhouse, comprise sensor and controller 2 and admission line 6, described admission line 6 is arranged on the bottom of booth, the top of described booth sets out feed channel 1, and the end of described outlet pipe 1 arranges the fan 5 of giving vent to anger, and in described admission line 6 and the described outlet pipe 1 a plurality of ventholes is set, described admission line 6 be connected outlet pipe 1 in the middle of connect a heat exchanger 3, the inlet end of described heat exchanger 3 arranges a supply fan 4; Described sensor and controller 2 comprise single-chip microcomputer 13, described single-chip microcomputer connects power circuit 7, temp. and humidity testing circuit 8, clock circuit 9, keyboard 10, LCD display circuit 11, warning circuit 12, forceful electric power driving and controlling circuits 14, and described forceful electric power driving and controlling circuits 14 is connected with described supply fan 4, the described fan 5 of giving vent to anger.
Further, it is control core that described sensor and controller 2 are selected singlechip chip AT89S52, and warm and humid sensor is selected SHT11.
The operation principle of present embodiment is as follows:
After the cold air suction of described supply fan 4 with the outside, enter booth by described admission line 6 behind described heat exchanger 3, regulate the temperature and humidity in the booth, described venthole is discharged to the described fan 5 of giving vent to anger with the hot-air of high humidity in the booth.
According to shown in Figure 2, the utility model master control device is selected the AT89S52 single-chip microcomputer, warm and humid sensor is selected SHT11, SHT11 is connected with the AT89S52 single-chip microcomputer by the two-wire serial interface circuit, at first utilize sensor to produce respectively the signal of relative moisture, temperature, then through amplifying, deliver to respectively A/D converter and carry out analog-to-digital conversion, calibration and error correction, by the two-wire serial interface data of relative moisture and temperature are delivered to the AT89S52 single-chip microcomputer at last, recycling AT89S52 single-chip microcomputer is finished nonlinear compensation and temperature-compensating.AT89S52 judges that whether the temp. and humidity value surpasses the upper lower limit value of setting, if transfinite, and output alarm signal then, warning circuit is rung, and gives the caution of people's sound, exports simultaneously control signal and drives heavy-current control and drive circuit works, control ventilation blower or electric heater work realize wet down or heat.
Further, used heavy current installation has electric heater unit and ventilation blower in the utility model, and voltage is 220V.Not electrically contact in order making between light current and the forceful electric power, to suppress electromagnetic interference, improve the reliability of control, heavy-current control and driver module adopt photoelectrical coupler.Shown in Fig. 3, adopt the photoelectric coupled device MOC3061 with zero cross fired in the circuit, the electrical isolation of late-class circuit before realizing.Humidity is above upper the prescribing a time limit of setting in booth, single-chip microcomputer P2.4 pin output low level signal, it is luminous to drive the MOC3061 interior light emitting diodes through 7407, output voltage is from obtaining output between its output 4 pin and 6 pin, bidirectional triode thyristor KS is subjected to triggering and conducting, air exhauster obtains the operating voltage of 220V, thereby the moisture in the booth is extracted out, and the humidity in the booth reduces gradually.When humidity in the booth is reduced to the lower limit of setting, single-chip microcomputer P2.4 pin output high level signal, the MOC3061 interior light emitting diodes is not luminous, and the voltage between its output 4 pin and 6 pin is 0, bidirectional triode thyristor KS cut-off, the axial-flow exhaust fan dead electricity quits work.The circuit that Control Shaft flows to blower fan and electric heater unit is identical therewith, pay special attention to be because of electric heater unit power larger, its required bidirectional triode thyristor KS will select high-current device, also can connect the solid-state relay realization to the control of electric heater unit behind photoelectrical coupler.
